Squeezes on ClickBank

Hey boys and girls,
I'm new to AM and I have a question. I've seen some products on ClickBank that have high gravity and popularity but on their landing page, it's a free report email signup. (Which will follow on with more emails from the vendor to the customer) How do you profit from that? Since it's not CPA, don't you just get impressions than sales?
Regards
